Glasgow's Dutch-built "amfibus" resumed testing today after being grounded for an unnecessarily deployed airbag. From the video on BBC's website, it looks just like a big yellow schoolbus, but runs in liquid and allows writers to make water puns.

I imagine that these amphibious busses will be useful in places that get hammered by rain, and be vital for cities that need flood evacuation. Each one costs £700,000 ($1.09 million), and will be used to replace ferries. So instead of taking a bus, a ferry, and then a bus again, you can just take one vehicle and pretend you're in MI6. [BBC
